  • Publication number: 20200190669
    Abstract: Methods and systems for direct lithographic pattern definition based upon electron beam induced alteration of the surface chemistry of a substrate are described. The methods involve an initial chemical treatment for global definition of a specified surface chemistry (SC). Electron beam induced surface reactions between a gaseous precursor and the surface are then used to locally alter the SC. High resolution patterning of stable, specified surface chemistries upon a substrate can thus be achieved. The defined patterns can then be utilized for selective material deposition via methods which exploit the specificity of certain SC combinations or by differences in surface energy. It is possible to perform all steps in-situ without breaking vacuum.

    Abstract: A silicon carbide crystal and a manufacturing method thereof are provided. The silicon carbide crystal includes an N-type seed layer, a barrier layer, and a semi-insulating ingot, which are sequentially stacked and are made of silicon carbide. The N-type seed layer has a resistivity within a range of 0.01-0.03 ?·cm. The barrier layer includes a plurality of epitaxial layers sequentially formed on the N-type seed layer by an epitaxial process. The C/Si ratios of the epitaxial layers gradually increase in a growth direction away from the N-type seed layer. A nitrogen concentration of the silicon carbide crystal gradually decreases from the N-type seed layer toward the semi-insulating ingot by a diffusion phenomenon, so that the semi-insulating crystal has a resistivity larger than 107 ?·cm.

    Abstract: According to one implementation, a fiber width adjustment device includes: a feeder and an adjuster. The feeder feeds a tape material in a length direction of the tape material. The tape material consists of fibers for a fiber reinforced resin after or before the fibers are impregnated with a resin. The adjuster has a path for the tape material. The path is formed by at least a bottom and a pair of wall surfaces. The interval of the wall surfaces decreased gradually. The width of the tape material which passed the path is changed by adjusting a part of the path. The tape material passes through the part of the path while contacting with the bottom and the wall surfaces.
